BALING-PRESS.

SPECIFICATION forming part of Letters Patent No. 720,148, dated February 10, 1903.

Application filed June 5,1902. Serial No. 110.333. (No model furthermore, to provide a baling-press which I shall be simple of construction, efficient and durable in use, and easy of manufacture.

With these and other objects in view, as

will appear as the invention is better understood, the same consists in the novel construction and combination of parts ot' a baling-press, as will be hereinafter more Yfully vdescribed and claimed.

In the accompanying drawings, forming a part of this specification, and in which like numerals of reference indicate corresponding parts, there is illustrated one form of embodiment of the invention capable of carrying the' same into practical operation, it being understood that the elements therein exhibited may be varied or changed as to shape, proportion, and exact manner of assemblage without departing from the spirit thereof, and in these drawings- A Figure l is a View in plan of a baling-press constructed in accordance with the present invention. Fig. 2 is a View in elevation, partly in section, showing more particularly the construction of the toggle-bar for actuating the plunger. Fig. 3 is a similar view showingrnore particularly the construction of the two-throw crank, with which are associated the pitman-rods connecting with the toggle-bar.

Referring to the drawings, 1 designates generally the frame of therpress, and 2 the plunger working in the baling-chamber 3', as usual. These parts may be of the common or any preferred construction, and as they per se form' no part of the present invention further description of them is deemed unnecessary. Connecting with the plunger is a two-knuckle toggle-bar composed of three connected members 4t, 5, and 6, the member 4 being asso- "through the joints thus formed serving to hold them assembled. Connected with the knuckles formed between the members 4 and 5 and 5 and 6 are two pitman-rods l2 and 13, in this` instance held associated with the knuckle by the assembling-bolts thereof, the

other ends of these pitmen being associatedv with a two-throw crank 14, working,r in a housing or boxing 15, as clearly shown in Figs. l and 3. The crank projects at one end above the boxing and has secured to it a sweep 16,l with which the horse is connected for operating the machine. In practice the pitmen will only be a few inches above the ground, so that as the horse travels around in a circle there will be no obstruction presented to his movements.

Under the construction shown it will be seen that double power is applied to the toggie-bar, inasmuch as when one pitman is pulling the other one is pushing, so that great compressive force can beimparted to the plunger with the output of but a small amount of energy on the part of the animal. A further advantage for employing two pitmen is that the throw of the crank is reduced, thus, while notdiminishing the length of the path of movement of the plunger, reducing to a minimum the danger of breakage of the cranks, which frequently occurs with singlethrow cranks, which have to be of such length to impart the necessary reciprocation to the plunger as to be Weak, and thus liable to frac.- ture. Y

While the baling-press of this invention is exceedingly simple of construction, it will be found highly efticient and durable in use and will rapidly and effectively perform the function for which it is designed.

Having thus fully described my invention,

TOO

what I claim as new, and desire to secure by Letters Patent, is-

1. A baling-press comprising a plunger, a two-knuckle toggle-bar associated therewith, two pitmen connected with the toggle-bar, and a two-throw crank for actuating the pitmen.

2. A baling-press comprising a plunger, a two-knuckle toggle-bar having one terminal associated with the plunger and the opposite terminal with a xed portion of the frame of the press, two pitman-rods associated with
